WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 336,353, dated February16, 1886.

Application filed November 11, 1885. Serial No. 182,463.

To all whom it may concern:

Be it known that I, OSCAR RUsT, a citizen of the United States, residingat Ithaca, in the county of Tompkins and State of New York, haveinventeda new and useful Improvement in IVell-Drilling Machines, of which thefollowing is a full, clear, and exact description.

This invention is an improvement in welldrilling machines, andparticularly in that class of such machines in which the drill-tool issupported on a rope and raised and lowered by the action of a camoperating on a lever supporting the pulley around which the drill-ropeis passed to the rope-drum.

The invention consists in certain features of construction andcombinations of parts, as will be described.

In the drawings, Figure 1 is a side elevation, Fig. 2 a top plan view,and Fig. 3 a front elevation, of my machine. Fig. 4 is a detailsectional view of one of the shafts and itspulleys. Fig. 5 is a detailperspective view of a part of the framing, the lever and the latchtherefor,together with the guide-pulley and its connection. Fig. 6 is adetail view of the bearing; Fig. 7, a similar view of a portion of themast, and Fig. 8 is a side elevation of the machine on the opposite sidefrom that shownin Fig. 1. The rope-operating lever A, the cam B, foractuating such lever, and the latch mechanism 0 G O, for locking saidlever out of the path of the cam, may be of ordinary construction, andneed no detailed description here. The drive and cam shaft D isjournaled at the rear end of the framing, and is provided with afriction drum, d. This shaft D may be driven in any suitable manner.Alongside of shaft D, I 3' ournal the intermediate shaft, E, which has asprocket-wheel, e, at its outer end. On the shaft E,I key or otherwisesecure the pulley F, and a pulley, G, is loosely sleeved on the shaft Ealongside of pulley F. This pulley G has a sprocket-wheel, 9, formed orsecured on one end. The intermediate shaft is geared with the rope-drumH through the medium of a shaft, I, having asprocket-wheel, j, geared byband J with the wheel 6, and also having a spur-pinion, i, meshed with agear-wheel, h, on the rope-drum.

the intermediate shaft is revolved by its fixed pulley F gearing withthe drive-shaft in the manner presently described, the rope drum By thisconstruction when.

(No model.)

will be revolved to wind the rope and raise the drill.

The slush-pump sleeve Iis suitably journaled to the framing,usually ontheshaft Land has a sprocket-wheel, i, geared by sprocketband I with thesprocketg of pulley G. I provide the shaft I with a ratchet, K, and pawl70, by which the drum may be locked from unwinding or be released to letout the rope, as desired.

A suitable brake, L, is arranged to engage a pulley, Z, as the shaft I,and such shaft also has a hand crank, M, by which it may be turned totighten the drill-rope.

An idler, N, is supported on one end of a pivoted lever, n, the oppositeend of which extends to the front of the machine. By depressing thelever the idler will be raised into contact with the drum (1, and pulleyF gearing the latter with the drive-shaft and communicating motion tothe rope-drum by the connections before described. A similar idler,0,and lever 0 are arranged in like relation to the drum d and pulley G sothe slush-pump spool may be revolved. Each of the idlers, it will beseen, is movable independently of the other, so that the slushpump spoolor the rope-drum may be revolved as desired.

It will be noticed that the location of the parts in the relations shownsimplifies the con struction and enables the spool or the ropedrum tobcquickly thrown into or out of gearing.

Heretofore when the rope-drum and slushpump spools have been gearedpositively with the drive-power the sudden shock incident to the workingof inventions of this class and the catching of tools within the well inbeing raised would frequently break the chains, resulting in the expenseand delay required for replaeing the broken parts.

By the friction-gearing arranged as described the gearing will slipslightly under such jars and strains, preventing the breakage beforereferred to, and also operating practically as a cushion for the entirewell rig, easing the jars and obviating the racking of such rig by thejars specified.

It will be noticed that the drum H is supported above the body of theframe-work in struts H, by which arrangement it is set suflicientl y farfrom the guide-pulley P to enable the rope to move from side to side ofthe drum to wind the rope properly thereon. In order to strengthen thesestruts and relieve their fastening-bolts from strain, I prefer to employthe upright braces h between the struts and the body of the frame-work,as shown most clearly in Fig. 1.

The mast Q is provided with lateral trunnions g, which are supported inopen bearings r in brackets R, secured to and projected from the mainframe on opposite sides of the mast. By this construction the mast maybe easily tilted back or may be removed from the bearings forconvenience in transportation or storage. The drill-rope Sis passed overa pulley at the top of the mast, down around guide-pulley-P and up, andis fastened to the drum H. To give the pulley free play and permit it tofollow the direction of the rope in winding on the drum, Iprefer toprovide such pulley with a clevis or loop, 19, connected with a clevisor loop, a, on the lever A by a connecting-link, T, as most clearlyshown in Figs. 1 and 5. By this construction a strong connection of theparts is provided, and the pulley may freely follow the direction of therope, and the latter will be prevented from slipping onto the rim of thepulley and cutting or wearing off by frictional contact.

The operation of my invention, except in the particulars abovespecified, is substantially the same as that of other machines of itsclasssuch, for instance, as shown in my Patents Nos. 257,766 and257,767, granted May 9, 1882.

Having thus described my invention,what I claim as new, and desiretosecure by Letters Patent, is

1. The combination,with the rope-drum and the shaft I, geared therewith,of the slush-pump spool journaled on the shaft I and pulleys connectedone with the shaft I and theother with spool thereon, the drive shaftand gearing whereby motion may be transmitted to either the slush-pumpspool, the shaft I, or to both of such'parts, substantially as setforth.

2. The combination of the drive-shaft having a friction-drum, theintermediate shaft, the rope-drum geared with said shaft, a pulley fixedon the intermediate shaft,a pulley sleeved on such shaft, the slush-pumpspool geared with such sleeved pulley, and idlers movable into contactwith the friction drum and the pulleys of theintermediate shaft,substantially as set forth.

3. The rope-drum and the shaft I, geared with such drum, and havingratchet K and brake'pulley Z, combined with the pawl k and thebrake-lever L, arranged and operating substantially as and for thepurposes specified.

4. The combination of the shaft D, the shaft E, having pulleys F and G,the rope-drum and the slush-pump spool geared with the shaft E, andpulley G, of gearing whereby either of pulleys F or G may be geared withthe shaft D, all arranged and operating substantially as as set forth. I

The above specification of my invention signed by me in the presence oftwo subscribing witnesses.
